Figure 5 is a top plan view of the structure shown in Figure 1 but showing the parts arranged for clamping rule borders or similar material in position to have the end portions thereof trimmed or squared; and

Figure 6 is a perspective view of. a detachable gauge member which is used in the practice or" the present invention.

The numeral 1 indicates a bed member which is carried by the standard 2 having the flat base portion 3 adapted to be mounted upon a floor or other foundation. The bed member 1 is formed to provide a pair of gurdeways 4 and 5, which guideways are arranged in right angular relationship with one another. Said guideways have the upstanding walls 6 (which walls 66 are at right angles to one another) and the horizontally disposed walls.7, whereby each of said guideways is adapted to slidably receive a plurality of rule borders or similar members; rule borders being shown in the drawings and being indicated by the numerals 8-8. Mounted adjacent to the guideway 5 is the relatively fixed boss 9, which is internally screw-threaded for the reception of the setscrew 10. The setscrew 1O occupies a position normal to the upstanding wall 6 of the guideway 5, whereby said setscrew 10 may securely hold the plurality of rule borders 8 against said upstanding wall 6. Mounted in cooperative relationship with the guideway 4 is the block 11, which is swivelly mounted in the horizontal wall 7 of said guideway 4. Said block 11 is adapted to have a rocking movement about a vertical axis for a purpose which will be referred to hereinafter. Said block is screw-threaded for the reception of a setscrew 12, which is adapted to cooperate with the upstanding wall 6 of the guideway 4 for holding a plurality of rule borders or the like in position. It will be noted from an inspection of Figure 1 that a plurality of rule borders are securely mounted on both sides of the machine.

The present invention contemplates the provision of a detachable gauge member shown in perspective in Figure. 6. Sald gauge member is indicated by the numeral 13 and comprises the head portion 14 and the shank 15. Said head portion 14 hasthe flat face 16 disposed in a plane at right angles to the axis of the shank 15, that is to say, said face 16 is disposed in a plane equiangularly positioned relative to the guideways 4: and 5. Said shank has a flattened portion 16. Said shank 15 of the detach able gauge member 13 is adapted to slide within the hole 17 which extends in a horizontal plane medially of the machine. A setscrew 18 is provided, the end of which is adapted to engage the flat portion 16 of the shank 15 to hold the gauge member 13 in at.- justed position. When not in use, said eetachable gauge 13 is carried in an unobtrusive position at the rear of the machine, as shown in broken lines in Figure 1, the shank 15 of said detachable gauge member 13 be ing located in the hole 15.

In order to position the gauge member 1.3, a micrometer gauge 19 is provided. Said micrometer gauge 19 includes the threaded shaft 20 adapted to engage with a similarly screw-threaded portion of the hole 17. Said shaft 20 is provided with the operating knob 21, said shaft 20 and knob 21 being provided with an axial aperture for receiving the pin 22, which pin has the head 23 adapted to abut against the extremity of the shank 15 of the gauge member 13. Said pin 22 is held in adjusted position relative to the shaft 20 by means of the setscrew 2 1. The knob 21 is provided with the peripheral scale 25, which cooperates with the index 26 secured to the bed member 1. It will be clear that as the knob 21 is rotated the head portion 23 of the pin 22 will be moved longitudinally for determining the position of the detachable gauge member 13. It will be clear that the Zero setting of the pin 22 of the micrometer gauge 19 may be adjusted by loosening the screw 241. In order to simplify the matter of adjusting the micrometer gauge member 19 for Zero setting, a spring may be pro vided between the screw-threaded shaft 2i) and the head 23 of the pin 22. Zero setting of the pin 22 will ordinarily be made with the detachable gauge member 13 in place, the location of said gauge member 13 being determined by the engagement of the face 16 of the head portion 14 of said gauge member with rule borders or the like clamped in the machine.

A cutter block mounting is indicated as a whole by the numeral 27. Said mounting 27 is pivotally supported for swinging movement about the axis of a vertical shaft 28 carried by the bed member 1 and base 2. Said mounting 27 is provided with a stop 29 adapted to engage the bed member 1 to limit swinging movement of said mounting toward said bed member. Said mounting is provided with opposed grooves 3030 for slidably receiving the blade holding member or cutter block 31, which cutter block is provided with a pair of tongues 32-32 slidably mounted within the grooves 3030. Pivotall'y carried by the mounting 27 is the lever 33, which lever is adapted to swing about a horizontal axis. Said lever 33 is provided intermediate of its length with a boss portion 3 1 having circumferential peripheral portions. Said circumferential peripheral portions ride between the abutment bearings and, as said lever 33 is raised or lowered, said lever, by reason of the engagement of the boss portion 3 1- with the bearing portions 3535, will communicate a reciprocatory movement to the cutter block 31 in a vertical direction. Located at the upper portion of the cutter block 31 is the blade 36 having a projecting edge adapted to more in cutting relationship with the members 88 to be operated upon. Said blade 36 may be held in place by any preferred means, setscrews 3737 being illustrated for this purpose. Positioned immediately below the. cutting edge of the blade 36 is the abutment 38 adapted to abut against the projecting portions of the members 83 to be operated upon, whereby to limit the depth of cut in any one cutting stroke.

Figure 5 illustrates the manner of using the machine when it is desired to square of? the ends of one or more slugs, rule borders. or the like. The guideway 1 is shown as being provided with an aperture 39 projecting through the upstanding wall 6 of said guideway 41-. The bed member 1 is provided with abutment portions 40-%10 presenting fa HY- 10 parallel with the axis of the hole 17; that is to say, the working faces l0 1O of the abutment portions rill-40 are in right angular relationship with the face 16 of the head 14- of the detachable gang member 13. which is another way of saying that the engaging faces -l-.0 l0 of the atument portions 40 l-O are in right angular relationship with the cutting plane of the knife 36 when said knife has been swung to the position in which the stop 29 is in abutn'ient with the front face of the bed plate 1.. As noted above, the block 11 is swivelly mounted, and by reason of the swivel mounting of said block. the setserew 12 may be presented at right armies to the engaging faces 40fl-0 of the abutment portions 40-4-0. In order to avoid the necessity of turning the setscrew 12 through a large number of revolutions when it is desired to use said setscrew for holding the borders or other articles will have their ends squared, itis a simple matter to indicate on the scale 25 the depth of the cut necessary to completely miter said rule borders without reducing the length thereof.

lVhen it is desired to miter a plurality of rule borders or similar articles, the detachable gauge 13 will be located in the machine, with the shank 15 thereof disposed in the hole 17. The rule borders or other articles to be mitered will be located in the guideways 4E and 5 with their squared end portions arranged in echelon. As noted above, the calibrations on the scale 25 will preferably be chosen to read directly according to the thickness of the rule borders 88, and the knob 21 carrying the scale 25 will be turned a sufiicient distance to project the head 23 of the pin 22 outwardly a sufficient distance to limit the inward position of the detachable gauge member 23 to the proper location. lVith the squared ends of the members 8-8 abutting against the inner face 16 of the head 14: of the gauge member 13, the setscrews 10 and 12 will be tightened up, whereby the members 8-8 will be held securely in place. The detachable gauge member 13 will then be removed and the cutting block 31 will be swung toward said members 88. The lever 33 will be held in its upper position and the abutment portion 38 of the cutting block 31 will abut against the ends of the members 88. lVith the abutment portion 38 in the abutting relation referred to, the handle 23 will be depressed, whereby a. small amount of material will be trimmed from the edges of the members 88. With the cutter block 31 held against the exposed surfaces of the members 88, the lever 33 will be given a re ciprocat-ing movement in a vertical direction, whereby the blade 36 will gradually trim down the projecting edges of said members 38. By reason of the engagement of stop 29 with the front face of the bed plate 1, the swinging movement of the blade 36 about the shaft 28 as an axis will be limited. As referred to above. the members 8-8 were positioned according to a setting of the scale 25 on the micrometer gauge 19, and this setting will be chosen to permit the said members 38 to project only a sufficient distance to permit the mitering of said members 88 without decreasing the length thereof. After one end of each rule border has been mitered, said rule borders may be transposed or reversed in position, so that the opposite ends may be mitered in the manner above described. In practice it is preferred to transpose the rule borders from one side of the machine to the other, in order that the printing faces of said rule borders may always be kept uppermost to avoid fracturing. lVhen it is desired to use the machine for squaring up or smoothing the end of a rule border or thelike, one or more of said rule borders will be clamped against the abutment portions 4:0"420, as shown in Figure 5. In ordcr to set said rule borders in position for squaring or smoothing the ends thereof, the detachable gauge 13 will be located with its shank in the aperture 17. The scale on the knob 21 will have one or more graduations corresponding to dimensions longitudinally of the screw-threaded shaft 20, so that the detachable gauge 13 may be conveniently set to position the members 88 for the amount of trimming required. It will be seen, therefore, that the scale 25 on the knob 21 will have two sets of graduations, one corresponding to the thickness of the rule borders or the like to be mitered and the other according to longitudinal dimensions measured along the axis of the pin 22.

Zero setting of the knob 21 is very readily accomplished. A rule border or the like may be set in the machine and the cutter block 31 may be operated until said cutting block has reached the limit of its swinging movement toward the bed plate 1. The cutter block may then be swung away from the bed plate and the detachable gauge 13 inserted in place. The setscrew 24 may be loosened on the pin 22, and with the head portion 23 of said pin 22 in abutting relationship with the extremity of the shank 15 of the detachable gauge 13 the knob 21 may be turned to a position in which the zero mark coincides with the index 26. The setscrew 24:

may then be tightened up.
